Although East African black athletes dominate endurance running events, it is unknown whether black and white endurance runners with similar racing ability, matched for training, may differ in their skeletal muscle biochemical phenotype. Thirteen Xhosa (XR) and 13 Caucasian (CR) endurance runners were recruited and matched for 10-km performance, average preferred racing distance (PRD(A)), and t...

BACKGROUND Western diets, which typically contain large amounts of energy-dense processed foods, together with a sedentary lifestyle are associated with increased cardiometabolic risk. We evaluated the long-term effects of consuming a low-calorie low-protein vegan diet or performing regular endurance exercise on cardiometabolic risk factors. METHODS In this cross-sectional study, cardiometabo...

this study aimed to compare the effects of high intensity and high volume training on lactate accumulation, time performance and vo2peak in 10-14 years old distance runners. 20 male endurance runners aged 12.5±2.32 years old and with a height of 154.62±3.27 cm, weight of 34.5±5.12 kg, maximum heart rate of 207.5±3.1 and vo2max of 36.45±3.22 ml /kg/min took part in the experiment. the experiment...

BACKGROUND Intensive endurance training has been associated with a high prevalence of symptoms compatible with asthma in elite athletes. It is not known, however, whether there is an association between the type of training for competitive events and the risk of asthma in highly trained athletes. METHODS Two hundred and thirteen track and field athletes, mostly from Finnish national teams, an...

OBJECTIVES To determine if the changes in specific skinfold sites induced by intense athletic conditioning over a three year period were associated with changes in running performance in high level athletes. METHODS Thirty seven top class runners (eight male and five female sprint trained, 16 male and eight female endurance trained) volunteered to participate in the study. The athletes were d...

BACKGROUND Beneficial and detrimental effects of various vegetarian and vegan diets on the health status are well known. Considering the growing background numbers of vegetarians and vegans, the number of vegetarian and vegan runners is likely to rise, too. Therefore, the Nutrition and Running High Mileage (NURMI) Study was designed as a comparative study to investigate the prevalence of omnivo...

The aim of this study was to analyze the injury incidence in young trail runners according body region, type, mode onset, and moment occurrence, both total detailed by sex. Thirty-five male sixteen female elite runners, aged between 15 22 years, completed a questionnaire regarding last 2 years. Comparison proportions within groups (all, male, runners) (male vs. computed using z Fisher’s exact t...

Background: The ACSL A/G single nucleotide polymorphism is associated with endurance trainability. It was previously demonstrated that AA carriers had a reduced maximal oxygen consumption (VO2 max) in response to training compared GG carriers, and this explained 6.1% of the variance VO2 max training. aim present study determine prevalence among soccer players. Methods: One hundred sixty-seven m...
